Deltor T

This product can be considered as the first Anilox roll used for flexoprinting. Its extremely simple structure is still widely employed in the printing industry, especially in the applications where a rubber roller for counter-pressure is used.

The galvanic chromium coating ensures a good resistance to corrosion and to wear, especially on solvent-based applications. As regards water-based applications, the resistance to corrosion is good. There might be particular cases where the characteristics of water from the mains might cause corrosion problems. In such cases, a roll structure of the Deltor N or Deltor R type is recommended.

Engraving is carried out mechanically on carbon steel. The anti-wear protection is ensured by galvanic chromium coating (standard hardness 890 HV), having a layer thickness from 10 to 30 microns.

The possible screens are listed in the technical data sheets for mechanical engravings.

Deltor BU

This product has been fully developed internally and is normally used to rebuild the diameter of worn rollers of medium and big sizes, which - after one or several refurbishments or due to heavy crashes or accidental impacts - require recovery to the original diameter.

By means of a welding cycle, one or several carbon-steel substrates - having a thickness which varies according to individual needs - are applied. After further working processes and thermal treatments, this substrate is mechanically engraved.

In order to ensure best protection against corrosion and to reduce the wear, a galvanic chrome coating (standard hardness 890 HV) with a thickness from 10 to 40 microns is applied after engraving. Instead of the galvanic chrome coating, it is also possible to use other treatments, such as Deltor Cer and Deltor Cabo.

The possible screens are listed in the technical data sheets for mechanical engravings.

Deltor BUI

This structure utilises the same manufacturing process as Deltor BU, but one or several layers of stainless steel are used instead of normal steel.

The advantage of this product is twofold since, besides the rebuilding of the original diameter, a normal roll of carbon steel can be converted into a roll coated with stainless steel.

This special product is mainly used in all those applications where problems due to the fluid being used during spreading or gluing are encountered.

Similar to the conventional BU, the thickness may vary according to the size of the roll; however for ensuring the necessary stainless features the thickness is never under 2,5/3 mm. After a series of further operations and thermal treatments, the substrate applied is engraved mechanically.

After engraving the roll can be considered completed, but for reducing the wear when necessary, there still can be different treatments, both thermal and galvanic ones and also flame processes according to the requirements of the customer.
